Pavegen taps pedestrians for power in East London (video)

by Joseph L. Flatley posted Oct 29th 2009 at 1:41PM

When we were kids, we assumed that in the future everything would be powered by tiny nuclear fusion reactors: automobiles, toothbrushes, time machines (apparently we read a lot of sci-fi from the 1950s). The truth, as usual, is more mundane than all that: some of the more promising advances we've seen in green energy has been kinetic, taking the movement of automobiles or the tides and converting it into electricity. Pavegen, for example, can be set in public walkways to generate as much as 2.1 watts of electricity per hour from the footsteps of grizzled pedestrians. Using marine grade stainless steel and recycled materials, just five of these bad boys distributed over a well-worn sidewalk should be able to generate enough energy to keep a bus stop going all night. If not put into nearby lighting, the units are equipped with lithium polymer batteries for storage. Currently being tested in East London, look for them throughout the UK in 2010. Video after the break.

US government lays out cash for wall-based, in-home 'smart meters'

by Darren Murph posted Oct 27th 2009 at 4:47PM

Google has its PowerMeter, Microsoft has its Hohm and Obama has his "smart meters." Got it? Good. Around two years after UK taxpayers began footing the bill for in-home energy monitors, it seems as if America's current administration is looking to follow suit. While visiting the now-open solar facility in Arcadia, Florida today, the Pres announced that $3.4 billion in cash that the US doesn't actually have has just been set aside for a number of things, namely an intelligent power grid and a whole bundle of smart power meters. Aside from boring apparatuses like new digital transformers and grid sensors (both of which are designed to modernize the nation's "dilapidated" electric network), 18 million smart meters and 1 million "other in-home devices" will be installed in select abodes. The idea here is to give individuals a better way to monitor their electricity usage, with the eventual goal set at 40 million installed meters over the next few years. Great idea, guys -- or you know, you could just advise people to turn stuff off when they aren't using it, or not use energy they can't afford. Just sayin'.

How-to: recycle your old gadgets

by Laura June posted Oct 27th 2009 at 1:56PM

We see a lot of gadgets come in the door here at Engadget. In fact, getting them in the door is actually the easy part... it's getting them back out that's a bit confusing. Recycling -- something that most of us do on a day-to-day basis with our trash -- is a bit stickier when it comes to gadgets. In recent years, however, most major consumer electronics companies have stepped up their games a bit and begun "take back" recycling programs of their own. There are a lot of resources out there if you want to rid yourself of old gadgets in a responsible way, but it can be a pretty overwhelming prospect, especially if (like us) you have an actual pile of old cellphones which has been growing since 1998. We thought about that a lot, and decided to try to make sense of all the wild masses of information out there on the internet, and to provide our readers a central location to look for all that information. Read on and see what we've come up with!

America's (newest) largest solar plant set to go live in Florida

by Darren Murph posted Oct 25th 2009 at 8:33AM

If all goes well, this 25-megawatt solar plant in Florida won't be America's largest for long, but it's not like we'd pass up the opportunity to let this $150 million facility bask in its own glory (and the sun, if we're being thorough) while it can. The Desoto facility is just one of three solar projects that Florida Power & Light is spearheading, and judging by the proximity of this one (in Arcadia) to the 75-megawatt facility planned for nearby Charlotte County, we'd surmise that the two are linked in some form or fashion. President Obama is expected to show up rocking a set of Kanye glasses underneath a welder's mask when the plant is fired up this Tuesday, and while it'll only provide power to "a fraction" of FP&L's customer base, it'll still generate around twice as much energy as the second-largest photovoltaic facility in the US of A.

Southwest builds first 'green plane,' Ma Earth shows her gratitude

by Darren Murph posted Oct 25th 2009 at 12:11AM

Southwest Airlines may not own a plane with a headrest infotainment system, but it's still far and away the most enjoyable commercial flight you'll find in the US of A (save for Virgin America, naturally). Granted, we'd like to see in-flight WiFi offered on a few more of its flights (read: 100 percent of them), but hey, we'll take free checked bags and friendly employees any day of the week. We'll also take fuel savings and environment stewardship, both of which Southwest is aiming to give us by creating the planet's first "green plane." By utilizing recyclable InterfaceFLOR carpet, weight-saving seat covers and life vest pouches, a lighter foam fill in the seats and aluminum (as opposed to plastic) seat rub strips, the newfangled Boeing 737-700 ends up some 472 pounds lighter than a conventional one. The savings? 9,500 gallons of jet fuel per year. We're not sure when the bird is expected to take her first voyage, but here's hoping a few others are hatched in the near future.

BMW makes the awesome look SIMPLE with leaning three-wheeler (video)

by Vladislav Savov posted Oct 12th 2009 at 5:44AM

BMW's latest concept isn't quite as far out as some of its earlier efforts, and the company has dubbed it SIMPLE, but don't let that fool you. Joining Nissan's Land Glider in a new trend toward leaning vehicles that have motorbike-like footprints, the "Sustainable and Innovative Mobility Product for Low Energy consumption" is said to have similar seating space to a BMW 3 Series coupe. Its space fighter appearance isn't just for show either -- with a drag coefficient of 0.18 and a weight of only 992 pounds, this bad boy is capable of harnessing a small internal combustion engine and electric motor to tear up the autobahn at up to 124mph. Zero to sixty in under ten seconds and 118 miles per gallon fuel efficiency fill out the sexy stat sheet, though sadly there are no productions plans as of yet. The concept is being exhibited in the BMW Museum in Munich, but if you can't make it over to Germany right now, there's a video for you after the break.

Hitachi's face-recognizing display turns off, saves power when you look away (video)

by Darren Murph posted Oct 10th 2009 at 12:31AM

CEATEC is a breeding ground for new innovations, and Hitachi made sure to get its name on the A-list with a simple face-recognizing television that seeks to save power whenever you glance away. Essentially, the prototype plasma on display packs an inbuilt camera that notices when your face is peering at it, and whenever you glance away, a power-saving mode goes into action. Unfortunately, that means that the panel goes black, and while we understand the point here, we can envision such a feature causing all sorts of rage around the house, particularly if you've got a handful of viewers trying to keep watch from a few feet further away than yourself. Hit the read link to have a look at how things work in practice -- here's hoping you can opt for the sound to stay on throughout the blackout, at least.

Ask Engadget: Best 'green' power strip out there?

by Darren Murph posted Oct 8th 2009 at 9:13PM

We know you've got questions, and if you're brave enough to ask the world for answers, here's the outlet to do so. This week's Ask Engadget question is coming to us from Randall, who isn't ashamed of his unbridled love for Ma Earth.

"I just moved into a new apartment and have been reading about all of the new power strips out there, especially the green ones. I was wondering if you had any suggestions about which "green "power strips are out there with decent joules ratings. And when I say green, I mean power strips that have the remotes or switches to turn off all electricity flowing to certain plugs and with at least 2 plugs that are always on. I was looking specifically at sub $50 because I will need two, but if that is not possible I could be convinced otherwise. Thanks!"

Don't be afraid to wave your green pride around here, folks. If you've got a power strip that nixes vampire drain and fits the bill, spill the details in comments below. It helps everyone to help the planet, ya heard?

Dow's POWERHOUSE solar shingles get along with non-solar siblings, your HOA

by Darren Murph posted Oct 8th 2009 at 10:04AM

Oh sure, massive photovoltaic installations on rooftops are nothing terribly new, but by and large, the ones we've seen are stuck on massive warehouses or elaborate stadiums in foreign lands. Dow Chemical is doing its darnedest to change all that with the introduction of the POWERHOUSE line of solar shingles. As you'd expect, these solar shingles are aimed at roofers looking to tip their hats to Ma Earth while providing shelter for well-endowed homeowners, and unlike most of the futuristic alternatives, these actually look somewhat similar to traditional shingles. Dow claims that "affordability" will be a feature when they become widely available in 2011, but we're understandably skeptical of such a claim given just how pricey solar roofs currently are (and you know, considering the company's for-profit standing).

Wheego Whip gets pictured, driven around at mind-blowingly slow speeds

by Darren Murph posted Oct 8th 2009 at 7:59AM

Given just how difficult it has been for even Chevrolet to get its all-electric gears going, we kind of wondered if we'd ever hear more about the Wheego Whip after it quietly faded earlier this year. Lo and behold, the low-speed city car has made an appearance at AltCar 2009, and after receiving about 100 orders, it seems the car is all but ready to begin pleasing those who shelled out just under 20 large for the privilege of a pink slip. Our good pals over at Autoblog Green were able to zip around in the car recently and serve up some impressions of the drive, and while it didn't seem to live up to the "Cadillac of neighborhood electric vehicles" claim, it definitely got the job done... at 25 miles per hour. Hit the read link for a gallery of shots and a fresh take on what a whisper quiet, low-speed driving experience is like.

Colored solar panels work without direct sunlight, double as PAR Can filters

by Darren Murph posted Sep 21st 2009 at 3:36AM

With eco-friendliness on everyone's mind, it's no shock to see more and more progress being made in the realm of solar. Shortly after hearing that boffins across the way were swapping carbon nanotubes for silicon, a Tel Aviv-based startup is now hoping to push its colored panels into the mainstream thanks to their ability to work sans direct sunlight. Granted, the tinted cells have only shown a 12 percent efficiency rate in testing, but they can reportedly be produced for around half of what a conventional panel costs. In essence, the cost savings comes from the dearth of silicon within, as GreenSun Energy has discovered that power can be generated by simply diffusing available sunlight over the whole panel and allowing nanoparticles to handle the rest. We'll invite you to visit the links below for the science behind it, but we're just interested in helping Ma Earth while replacing every windows in our apartment with a stained glass alternative.

Volkswagen L1 concept is crazy efficient, could ship in 2013

by Darren Murph posted Sep 18th 2009 at 5:33AM

Look, it's a well-known fact that the world is ending in either 2012 or when the Large Hadron Collider starts back up (whichever comes first). But, assuming neither of those scenarios actually cause planet Earth to fold in on itself, you should have some pretty swank Volkswagens to choose from in 2013. Just days after hearing that the highly-anticipated E-Up! concept would be landing in around four years, VW is now proclaiming that the L1 concept you see above could also hit production at the same time. What's odd, however, is that the automaker is already calling this the "most fuel-efficient automobile in the world," but at 170MPG, you'd think the suits at Chevy would have a thing or two to say about it. At least in theory, the hybrid TDI vehicle can cruise 100 kilometers on just 1.38 liters of diesel, but we'll wait until the EPA gets a go before buying in completely.

Cornell gurus look to carbon nanotubes for efficient solar cells

by Darren Murph posted Sep 17th 2009 at 10:21PM

You know what we love? Solar-powered gadgets, and carbon nanotubes. Oh, and Ivy League schools. Boffins from Cornell University are now looking to use the multifaceted carbon nanotube instead of silicon to develop efficient solar cells, and judging by the glacial pace at which solar cell efficiency is improving, we'd say the sector could use the boost. The researchers have already fabricated, tested and measured a simple solar cell (called a photodiode, just so you know) that was formed from an individual carbon nanotube. The tube was essentially a rolled-up sheet of graphene, and while the inner workings would take days to explain, the gist of it is this:

"The nanotube may be a nearly ideal photovoltaic cell because it allowed electrons to create more electrons by utilizing the spare energy from the light."

So, solar-powered F-350 trucks are now a possibility for next year, right?

Toyota's plug-in hybrid Prius gets pictured, detailed further

by Darren Murph posted Sep 13th 2009 at 4:01PM

The future, kids -- we're living in it. Sensationalism aside, we are pretty jazzed to hear that Toyota's long-awaited, much-teased plug-in Prius hybrid will be making its bona fide debut to the public next week. The image above is expected to be near-final, though we're reserving judgment until we see if the actual model on stage is plastered with 80s era stick-on graphics. Of note, the Hybrid Synergy Drive system has been upgraded for this whip, enabling it to slowly rocket from 0 to 62 without using a drop of gasoline. Once there, it can cruise for up to 12.5 miles in electric mode, and should you need to juice it back up, it'll take 1.5 hours when charged from a 230V source. Further details are expected to flow as Frankfurt heats up, though the whole "not shipping to retail until 2012" kind of puts a damper on our excitement.

Mercedes-Benz Vision S 500: it's the plug-in hybrid for old people

by Darren Murph posted Sep 12th 2009 at 9:36AM

Look, you won't find a bigger bunch of fans of the C63 than this here crew, but man, that massive "plug-in hybrid" logo might as well say "70+ aged drivers only, please." For everyone not interested in scooping up a Tesla Roadster, Chevy Volt or some other eco-friendly whip that they can't afford, there's the Mercedes-Benz Vision S 500. Made official this week during the run-up to the impending Frankfurt auto show, the 3.5-liter PHEV aims to grab the eyes of those who value class, comfort and luxury, and while this whole "gas mileage" thing is still very much in the air with this type of vehicle, early estimates peg the MPG rating at around 70. M-B has gifted the car with an 18-mile electric range, but most everything else is being veiled in secrecy until the full reveal next week.
